DETACHABLE BOTTOM FOR OVENS OR BROILERS Gustav Klein, Melrose Park,'Pa., assignor to Caloric Stove Corporation, Philadelphia, Pa., acorporation of Pennsylvania Application March 22, 1948, Serial No.16,203

2 Claims.

it is' not readily accessible for adjustment and cleaning withoutremoval of the bottom wall of the oven compartment. Also, in cookingstoves, foodmay spill andgrease may drip on the bottom walls of the ovenand broiler compartments and where such bottom walls are not readilyremovable, keeping these bottom walls clean is difficult. In order topreventwarping, the bottoms of conventional stoves aresecurely locked inposition and can, therefore, only be removed and reinstalled by theexercise of skill and efiort beyond those of the average householder.

It is therefore the object of the present invention to provide animproved stove structure whereby the bottom of the oven compartment isadequately secured against warping and may be removed and reinstalledwithout any skill and with very little effort, whereby access may be hadto the burner and whereby the oven compartment bottom may be easilycleaned.

In the accompanying drawings:

Fig. 1 is a diagrammatic front elevational View of a cooking stove.

Fig. 2 is an enlarged vertical sectional view,

taken on a plane at a right angl to line 2-2 on Fig. 1, showing thedetachable bottom wall structure embodying my invention.

Fig. 3 is a section on line 3-3 on Fig. 2.

Figs. 4 and 5 are similar to Fig. 2 showing the manner in which thedetachable bottom wall may be removed and installed.

The stove shown in Fig. 1 includes an oven compartment Iii, a broilercompartment l2, and storage compartment [4. Since the structure of thestove, except as hereinafter described, forms no part of the presentinvention, it is not shown nor described.

As shown in Fig. 2, the detachable bottom includes a Wall I6 havingfront and rear pendent flanges l8 and 20 which are adapted to rest onfront and rear horizontal ledges 22 and 24 carried by the inner faces ofthe front and rear walls 26 and 28 of the stove, respectively. Measuredfrom front to back, the bottom [6 is shorter than the distance betweenthe front and rear walls 26 and 28 so as to leave room for installationof an arcuate flat spring 30. The flat spring 30 is suitably secured asat 32 and its ends 34 slidably bear against the rear pendent flange 20,as

best shown in Fig. 3. The space between the pendent rear flange 2B andthe rear wall- 28 is closed by means of a strip 36 which may be aseparate piece suitably secured in position or which, as shown, may bepart of the ledge 24. Conveniently, the ledge 24 is secured in positionby the bolt 32 which also secures the spring 30in place.

The front wall 26 carries" a horizontal,- inwardly projecting strip 31which overlaps the front edge of the bottom IS and serves as a keeper toholdthe bottom iii in position. The strip 31 may be a separate piece orit may be part of the supporting ledge 22.

The bottom It is also provided with a manipulating handle 38 which ispreferably recessed, as shown, so as to be flush with the upper surfaceof the bottom of the oven.

The bottom It may, conventionally, be provided with a second Wall 40which is spaced from, and covers a major portion of the underside of thebottom H5. The wall 40 is secured to the underside of the bottom 16 asat 42. The rear edge of the wall 40 rests on the supporting ledge 24, asshown in Fig. 2.

To remove the oven bottom [6 from the position of Fig. 2, the operatorgrasps the handle 38 and pushes the bottom I6 rearwardly, or to theright in Fig. 2, against the tension of the spring 30, until the frontpendent flange I8 clears the keeper 36, as shown in Fig. 5. The frontedge of the bottom It is now raised to the position of Fig. 3 and thebottom is pulled out through the front access opening of the ovencompartment.

i After it has been cleaned, or after the burner has been serviced, thebottom It is reinstalled by pushing the rear edge thereof, against theaction of the spring 3|] until the inner, vertical front edge of thebottom [6 again clears the keeper 31. The front edge of the bottom [6 isnow moved to a position under the keeper 3! with the flange l8 restingon the supporting ledge 22 as shown in Fig. 2. In this position, thespring 30 urges the bottom I6 forwardly, or to the left as viewed inFig. 2, and thus firmly holds the bottom in position.

The bottom of the broiler compartment is preferably constructed in thesame manner but since the structure would be identical with that shownfor the oven compartment, no further illustration or description isneeded.

Also, While in the structure shown, the spring is on the rear wall, itis Within the scope of my invention to place the spring 30, the rearledge 24 and the strip 36 on one of the side Walls of the ovencompartment and the supporting ledge 22 and the keeper 3'! on theopposite side wall.

The space between the walls It and 40 is filled with any suitableinsulating material thus preventing overheating of the portions of thewall I6 directly above the burner.

By the arrangement shown the front and rear marginal portions of thebottom are engaged by the overlapping strips 36 and 31 (the clearanceshown between the strip 36 and the adjacent end of oven compartmentbottom being very small) and thus any tendency of the bottom to warpwhen heated is counteracted. In other words I have produced a novelstructure in which the bottom of the oven compartment is protectedagainst warping and is completely detachable.

What I claim is:

1. A wall structure defining a compartment having'a bottom opening, aclosure for said opening, a U-shaped bracket carried by each of twoopposite walls of said compartment with the bights of the U-shapedbrackets abutting said walls, the length of said closure being slightlyless than the distance between the juxtaposed ends of the upper limbs ofsaid brackets and the spaces between the upper and lower limbs of thebrackets being slightl larger than the thickness of said closure wherebyon being tilted, one marginal portion of the closure can be insertedinto one of said U-shaped brackets and then the opposite marginalportion can be inserted into the other of said brackets, whereby theclosure is supported on the lower limbs of said brackets with the upperlimbs of said brackets overhanging said marginal portions, and a springcarried by one 4 of said walls and operative, when said closure issupported by said brackets, to bias said closure against the oppositewall.

2. A wall structure defining an oven compartment having a top wall andvertical walls and having a bottom opening, a first supporting ledgecarried by and projecting inwardly from a first vertical wall, a secondsupporting ledge carried by and projecting inwardly from a secondvertical wall opposite said first vertical wall, a keeper carried bysaid second vertical wall and projecting inwardly therefrom invertically spaced relation to said second supporting ledge, a closurefor said bottom opening, the length of said closure being less than thedistance between the inner edge of said keeper and the first wall sothat by tilting said closure one marginal portion thereof can beinserted between said second ledge and said keeper so as to rest on saidsecond ledge, and the other, opposite marginal portion of said closurecan be lowered to rest on said first ledge, and a spring carried by oneof said walls and operable, when said closure is seated on said ledges,to engage the adjacent marginal portion of said closure and to bias saidclosure toward the opposite wall.
